Title: Variable value indicator devices
Inventor: GELENIUS ROBERT BRUCE
IPC: G01D5/20
Filed: 1971-04-22
Abstract: 1283167 Measuring voltage GENERAL MOTORS CORP 22 April 1971 [6 May 1970] 10672/71 Heading G1U [Also in Division H3j A variable voltage indicator comprises two mutually perpendicular stator coils which cooperate with a permanent magnet rotor carrying a pointer, and two associated circuits each of which, in response to the application of the voltage to be indicated, causes current to flow through its associated stator winding, the currents being such that the direction of the resultant magnetic field produced by the windings varies linearly with the applied voltage. The description relates almost entirely to the two circuits, the first of which, in response to a steadily rising applied signal voltage (horizontal axis, Fig. 3) causes a current to flow in its associated coil which follows a curve 86, and the second of which causes a current to flow which follows a curve 88. The characteristic 86 is produced by a transistor 22, Fig.1, which has an output to a linear current amplifier stage comprising two transistors 32, 38, between which the associated stator coil 16 is connected. With an applied signal voltage of zero, the transistor 22 is saturated and the output signal from its collector is such that transistor 32 is just not conducting and maximum negative current flows through the coil 16 via a resistor 40 and transistor 38. As the input signal voltage rises, the voltage applied to the base of transistor 32 rises linearly with it, until diode 26 becomes reversed biased. This occurs at ordinate B on curve 86, Fig.3, and during the period up to ordinate B the current through the coil 16 increases linearly with the signal voltage, where current flow from right-toleft through coil 16 is arbitrarily referred to as "positive". Diode 26 having become reversed biased, no further change in the voltage applied to the base of transistor 32 occurs, even though the input signal continues to rise, until transistor 22 starts to come out of saturation, which occurs at ordinate C on the curve 86. After this point, transistor 22 progressively conducts less until eventually, at ordinate E, it is fully cut-off. After this, no further change in the voltage applied to the base of transistor 32 occurs even though the input signal continues to rise. A similar circuit 14 described for applying current to the second stator winding 18 of the indicator. The biases applied to this second circuit 14 are so chosen that its characteristic 88, Fig.3, is phase displaced as shown, with respect to characteristic 86 for the first circuit. A modification is described, Fig. 5 (not shown) in which firstly the positive terminal of the signal source is connected to the positive battery supply line via a potential divider (90, 92) the tapping point of which provides a signal to the base of transistor 22, and secondly, the diode 26 is omitted, the plateau from ordinates B to C arising from saturation of transistor 32.

Abstract: 1,256,307. Protective arrangements. BLAUPUNKT-WERKE G.m.b.H. 28 Feb., 1969 [2 March, 1968], No. 10695/69. Heading H2K. An overload protective arrangement for a stabilized D.C. power supply circuit which has a thyristor 10 to which control pulses are fed from a control transistor 28, comprises a resistor 21 connected in a current path of or from the supply circuit, a transistor 40 controlled by the voltage across the resistor 21 and a "switching" diode 49 controlled by the transistor 40 so as to apply a blocking voltage to the base of the control transistor 28 when overload current flows through the resistor 21 which might be a cathode resistor of the line output valve of a television receiver. Normally the transistor 40 is conducting and the current from a source U H  flowing through resistors 48, 47 and the transistor 40 provides a voltage at the junction of these resistors to block the diode 49. Under overload conditions, the voltage across the resistor 21 is sufficient to bias the transistor 40 to non- conduction and current can now flow from the source U H  through the diode 49 and voltage divider resistors 24, 25. The control transistor 28 is now biased so that it cannot conduct, the thyristor 10 receiving no further control pulses.

[Classes 83 (ii) and 83 (iv)] [Also in Group XL] Winding.-An indirectly heated cathode for an electric discharge tube is formed by rolling or otherwise shaping a blank into a body of two or more layers. Cathodes of internal diameter smaller than 1 mm. may thus be made having a total wall thickness equivalent to the normal and without seams which tend to open due to heating during operation. The blank may be of 50 microns or less in thickness, e.g. 25 microns. The cathode may consist of tungsten or molybdenum or may be formed with a top layer of a material of low heat-radiating capacity such as copper with a substratum of a material having a low heat conductivity such as nickel or chromium-nickel, the top layer not covering the substratum of the upper and lower ends of the cathode. The seam may be welded at one or more points. The cathode may be made by pushing a blank 7 down a support 10 on to a paper strip 1 which passes from a supply roll 2 to a roll 5 through rollers 3, 4 and over a pin 6 drawn against the rollers 3, 4 by the strip. The blank is thus wound on the pin 6 whose diameter is that of the inner diameter of the cathode. The blank may be supplied at 9 so that the cathode may be suspended from the insulating member on which it is mounted. In another form the blank may consist of nickel and copper parts joined end to end.

Abstract: 848,923. Electrical digital data-storage apparatus. STANDARD TELEPHONES & CABLES Ltd. April 3, 1959 [April 8, 1958], No. 10985/58. Class 106 (1)] A rotatable storage device, as described a magnetic drum, carries storage tracks each having a number of word storage sections and a control track WCT which carries a first series of control recordings each defining the point of commencement of a word section on the storage tracks, and a second series of control recordings each comprising an address of a word section within its storage track, the address recording being read by a transducing device at a time bearing a predetermined relationship to the time at which the word section to which the address refers is in operative relationship with a transducing device associated with the storage track containing the word section. In the drum described each storage track has 32 sections each capable of carrying 33-bit lengths words with a 7-bit inter-word gap. The first series of recordings appear at element position 31 of each section, the addresses at positions 1 to 5. Additionally a clock track providing element timing pulses WT is carried by the drum. A " 1 " on WCT produces an output PR for one element time which is gated through G2 to a shift register P32, P33 ... P40, P1 ... P30 if a control P1-P5 is off indicating that the digit is not part of an address. The register is used to identify any element within its word period and the digit is shifted by gating the output of P32 to P33, and to turn P32 off, by means of the clock pulses TW. This is shown generally within the chain-dotted rectangle. The actual output from the track may be used to identify P31. If the digit is an address digit it is gated to a utilization circuit SS which is preferably a shift register. The control P1-P5 is actuated by pulses from the shift register P1 to P40. The address recordings may be duplicated on WCT. Specification 799,793 is referred to.

In A.C. circuits this occurs at the zero of the current cycle. Specification 344,867 is referred to.
Patent GB-454636-A (GB)
Title: Manufacture of keto-dicarboxylic acids and their lactones
IPC: C07C51/09
Filed: 1935-04-10
Abstract: Keto-dicarboxylic acids and their lactones are prepared by heating under substantially anhydrous conditions a dicarboxylic anhydride in the presence of a decarboxylating catalyst. Substances which are used as catalysts are those materials which are known to act as decarboxylating catalysts.  Such materials include compounds of metals of the sixth group of the periodic system particularly compounds of chromium, as well as compounds of other metals such as zinc, aluminium, copper, nickel silver and sodium.  The oxides, hydroxides and carbonates of such metals have been found to be particularly useful.  It has also been found that a mixed catalyst is more effective than a single catalytic compound.  A preferred mixed catalyst is prepared by mixing one mol. of the oxide or hydroxide of copper with 3 mols. of the oxide or hydroxide of chromium and adding thereto 3 mols. of anhydrous sodium carbonate.  As anhydrides suitable for use according to the present invention, there are mentioned phthalic anhydride succinic anhydride or a substituted phthalic anhydride such as chlorophthalic anhydride.  The reaction temperature varies with the catalyst used, although it is preferred to conduct the reaction with the anhydride in the liquid state.  The reaction may, however, also be conducted with the anhydride in the form of vapour.  After the reaction, the reaction mixture is extracted with alkali and the keto-dicarboxylic acid formed is liberated with hydrochloric acid and crystallized from petroleum ether. Alternative procedures for working up the reaction product are described.  The acids of the present invention are suitable for the preparation of alkyd resins either as the only polycarboxylic acid used, or in combination with other polycarboxylic acids. The resins so produced are characterized by improved solubility in varnish solvent vehicles and by the production of quick-drying hard and durable films.  They are valuable for the preparation of coating compositions.

Title: Signal translating devices utilizing semiconductive bodies
IPC: H01L29/00
Filed: 1952-05-02
Abstract: 723,808. Transistors. WESTERN ELECTRIC CO., Inc. May 2, 1952 [May 5, 1951], No. 11144/52. Class 37. In a transistor comprising a semi-conductive body of the same conductivity type throughout, noise effects are reduced by providing a zone or region of higher conductivity than in the remaining or bulk part and making the collector connection to the high conductivity region. It is stated that in such a transistor interference or noise component charge carriers of like sign to those injected at the emitter and generated sporadically in the bulk part or region are prevented from flowing to the collector by a barrier presented at the interface between or junction of the high/low conductivity regions. The invention is described with reference to N- type semi-conductive material with the high conductivity region denoted by N + and the low conductivity region by N so that interference or noise holes generated sporadically in N are prevented from reaching the collector by the N/N + interface barrier. The N + zone or region may be a crystal boundary. In the example, shown, Fig. 1, a germanium wafer 20 comprises N zones 21, 22 on opposite sides of a narrow N + zone 23 and the collector point 26 bears directly upon the N + zone and the emitter 25 upon N region 21. The ohmic or base electrode consists of coating 24 covering one face of wafer 20. In a second example, Fig. 4, an N-type block 200 has an N + top layer 32 which is receptive of both emitter 25 and collector 26 point contacts and the N region bears on ohmic base 24. An auxiliary point contact may be provided as at 33, Fig. 7, at the N/N + interface and is polarized to control the barrier magnitude. In a further modification to Fig. 4 the two-point contacts 25, 26 bear against the side of the block, as shown, Fig. 6, with 25 bearing against the N region and both adjacent the N/N + interface; an auxiliary connection on the interface as in Fig. 7 may be included. The invention may also be embodied in filamentary transistors as demonstrated in Figs. 8 and 9 wherein the N + zone 32 extends along the filament portion and into one enlarged end portion 35 ; the emitter is a point contact on N + in the filament portion and the collector is a coating on N + in enlarged end portion 35 and the base or ohmic connection is made to the wholly N end portion 34. The invention may be put into effect using silicon instead of germanium. The theory underlying the invention is explained utilizing Fermi-Level diagrams, Figs. 2 and 5 (not shown), and the noise improvements are illustrated with the aid of performance graphs, Figs. 10A and 10B and Figs. 11A and 11B (not shown). Specifications 694,021, 700,231, 700,236, 706,849 and 706,858 are referred to.

Title: Polypropylene monofilaments and a method of preparing them
IPC: C08F210/00
Filed: 1958-04-10
Abstract: Monofilaments consisting of or containing a major proportion of highly crystalline isotactic polypropylene are produced by an extrusion process in which the temperature at the input end of the extruder is 20 DEG -100 DEG C. above the melting point of the polypropylene and decreases along the length of the extruder so that the temperature at the extrusion head is 0 DEG -40 DEG C. above the melting point of the polypropylene.  The temperature at the input end of the extruder is preferably 200 DEG -250 DEG C. and at the extruder head 170 DEG -180 DEG C.  The extruded filaments may be quenched in a bath of water maintained at a temperature of 40 DEG -50 DEG C. and may be stretched continuously or wound up on bobbins and subsequently stretched.  The filaments may be stretched at a stretch ratio between 1:7 and 1:9 between two slow rollers and two fast rollers between which is placed a thermo-controlled metal plate or a heated bath of liquid, e.g. water, at a temperature between room temperature and the melting point of the polypropylene, e.g. at 130 DEG C.  After stretching, the filaments may be subjected to thermal stabilization either under tension or in a state of controlled or free shrinkage. If the filaments are to be used as bristles in brushes, their ends may be conically tapered by periodically varying the speed of the collecting rollers immediately after spinning.  The filaments may be used for making filters, nets, fishing lines, marine ropes, tapestries, handbags, suitcases, shoes, tents, doormats and air carpets.
